Solasta's UI is clean, clear, intuitive, easy to read and follow, and remarkably bug free in its execution. BG3's UI is exactly none of those things at the present time.
The only complaint I've ever seen anyone make about Solasta's UI is that they feel its aesthetic doesn't fit with a fantasy D&D game, or that they simply don't find it aesthetically appealing. I've never seen any complaints related to its actual function.
No you should have seen the complaints about it. Just been a long time since everyone had this discussion in another thread. Solastas UI looks like it belongs in a mobile game & everything is hidden in popup menus. Generally seems like a theme.
I'm a fan of the current customizable action bar. Still think they could remove the center portrait to reduce space. Make the mini-map able to hide, like how combat log is.
